NOTE − Circuit 1 Minimum Circuit Ampacity includes the Blower Motor Full Load Amps.1 Electric heater capacity only � does not include additional blower motor heat capacity.2 Amps shown are for blower motor only.3 Refer to National or Canadian Electrical Code manual to determine wire, fuse and disconnect size requirements. Use wires suitable for at least 167°F (75°C).4 Bold text indicates that the circuit breaker on �CB" circuit breaker models must be replaced with size noted.5 All 575v electric heaters are used with 460V blower coil units. A 575V to 460V Step-down transformer for the blower coil unit is furnished with all 575V electric heaters.6 Blower motor is rated at 460V.7 HACR type circuit breaker or fuse.
